Where do I find parts for a car window?

The car window is going up crooked intermittently, leaving a gap at the back of the window. Took the door panel off, checked the cable (not frayed), checked the motor (works fine) and nothing is broken mechanically. I see some kind of guides that look bad and need help with figuring out what they are "called" because I can't find them, even on the car manufacturer's parts website. I don't see them on the diagrams at all.

One is a white rubber piece that looks like some kind of roller with a screw going through it that holds it to the window. I didn't see one on the rear, but there might be one of these on the rear since there are two black guides at the top.

Apparently as the window goes up, it hits on this black guide and the white roller guides it along:

As you can see, the white roller is basically sawn in two and instead jams against the black guide when the window goes up. This same setup might be on the back of the window, as well. The black guides along the top of the door… There's one in the front and one in the back. Both of the black guides look cracked and you can see it in the photo. I need to replace both of those black guides as well as the one (or two) white rollers. Just can't find them anywhere.

What do they generally call these? I'm fine with ordering it online, but it isn't listed on the Ford Parts website in the diagrams. As you can see, the

You have no idea what you are doing. Bring it to a repair shop. It's worth it.

Try your local Ford dealer, or ask around on Ford club forums.

They may be made from nylon. If you can't buy them, a machine shop could make replacement parts, but it could be expensive. Also, if it's an older car you may need to clean the channels. If the channels are dirty, the dirt can cause trouble even after replacing the rollers.

The "Help" stand at Autozone, Advance or Pep Boys OR,… Ford parts counter.

As this is a part that you will get nowhere other than a main dealer then if you visit them and explain they will be able to sort it out. It may not be available as a stand alone part but as part of an assembly or kit.

The white part looks to be a stop for the window height when it's all the way up. Usually when a window gets tilted the window regulator is bad. Take your VIN and go to the dealer parts department. They will have a complete photo of all the parts. Advance Auto has a good window regulator at a reasonable price.

At a car store.

Go to a car dealership and get the new parts. If unavailable, go to an auto salvage yard (junkyard). Sometimes AutoZone or O'Reilly or similar auto parts store has or can get them.

GO in PERSON to a Ford dealership!
Go to the Parts Department and ask.
If the parts are not available, go to the dealership Body Shop and ask them where THEY get window parts.

You are too ADDICTED to your computer!
